If a dealer is working on a tractor or the injection pump, they might dyno it or adjust it. Tractors come from the factory ready to go to work. They might need some final assembly but not with the engine. When I had my 1965 135 in the shop about 20 years ago, I asked them to dyno it. I was standing right there and it put out exactly what it said it should according to published H.P. and what the service manual said it should be. It had the factory seal on it. Turning up a pump reduces the life of the engine and also increases fuel consumption. In the time when 135's were selling in record numbers, I'd think the dealers were pretty busy just getting them out to customers. Usually when someone wants a new tractor, it's because they want to upgrade for what ever reason, not because they have money burning a hole in their pocket. With the price of fuel today, I would think that people want as efficient of tractor as possible. The Perkins engines of 40 years ago are still some of the most fuel efficient engines ever made. You're trying to dispute the sales and reputation of a tractor you've never owned. Are you going to say that all your neighbors that seem to have all these 135's laying in the weeds are all wrong because they bought them in the first place? You are grasping at straws in your argument. 100 series Massey's sold in huge numbers because they were outstanding tractors! They are still highly sought after and recommended to people. How can you dispute that? Dave
